Mobile Hidden Camera Android App (Video and Still)

Via Superguy. This free app does a lot of cool things like killing the shutter sound and viewfinder, sending the file to a folder no one would think to obviously look, etc. etc. You can set the screen to be blank (black), tap it, and start shooting.

Even the launch icon looks like a boring generic app that has nothing to do with photos or video! Took me a while to find it at first.
